Research Progress on Coping Strategies of Cognitive Impairment after Cardiac Surgery: A Systematic Review of Literature.

Abstract

Postoperative cognitive dysfunction (POCD) refers to a complication of neurological dysfunction after surgery, including one or more changes that are significantly lower than those before surgery. The purpose of this study was to review the coping strategies and risk factors of POCD.A systemic research was conducted searching Pubmed, web of science, MEDLINE and other websites with the keywords of cardiac surgery, cognitive impairment and POCD. Multiple factors have been associated with the treatment of POCD, including anesthetic, choice of analgesic drugs, anti-inflammatory drugs, erythropoietin, atherosclerosis, emotional factors, surgical and other factors. Targeted treatments are carried out for risk factors that may affect POCD prevention, such as anesthetic drug prevention, anti-inflammatory drug prevention, and intraoperative prevention and other preventive measures are aimed at reducing the incidence of POCD after cardiac surgery.
